Which programming software have you used?
My experience has not been consistent with these observations. I've had no
trouble programming F84's using the Ludi design and the measured voltage on
the my serial port is just below 10 Volts. It has also worked with my
laptop. In fact, I've built 2 dozen Ludi's and all of the them have
worked. I've tried them on over a dozen different computers and only found
one that didn't work. The ones that did work included everything from my
486DX2 laptop (running Win95) to 75 MHz pentiums and 233 Mhz pentiums
running Win95, to a 200 MHz Pentium Pro running Win98 to a 450 Mhz Pentium
II running WinNT. All worked. It does matter a great deal which
programming software you use though.

With the Ludi, I've had good success with either PIX or PicProg if I was
using Win95 or Win98. For use under WindowsNT, I wrote my own program that
would run from the command line so I could integrate it with MPLab. It
works on many, but not all computers (seems to have some trouble especially
with AMD processors, but I'm not sure why). It will also run under Win95
and 98. It uses WinAPI calls to manipulate the serial port lines (rather
than writing directly to the hardware). This allows it to work under NT.
It's very experimental at this point. It's called PIXIE and is available
at the TAPR FTP site:
I am trying to keep track of which computers this approach works on and
which it does not, so if you decide to try it, please drop me a note and
let me know whether it worked for you and what processor and operating
system you are using.

I've had really good results with my ludipipo programmer, and it's so cheap
and easy to build. I've used it on both an AMD 5x86 133 and Pentium 166,
and it's worked fine. I'v used PIX, PicProg, and Picser, and they're all
good programs. I guess my favorite is PIX, though I do like the
convenience of the Windows interface on the other two.
